h/w help

helpme · 10-19-2003, 09:45 AM

Hi,

I spent about 4 hours and im stuck on one aspect of the program that i am writing .. its a h/w assignment

so this is the problem, i need to find a way to tell the user to enert 10 character - thats easy.

heres the hard part - or thats what i thinnk is hard

the program must scan the input for several letters, then subsiture other letters in thier place.

lets say the user enter

abchdish ui

the program would replace the letter a with lets say #

so the output would be

#bchdish ui

thanks..

You should be able to work your way through this code. Unfortunately, it uses conio.h which is not an ANSI standard header.

Code:

#include <stdio.h>
#include <conio.h>	//Not ANSI compliant

int main( void )
{
	int input;

	do{
		input = getch();
		if( input != 'a' )
			fputc( input, stdout );
		else
			fputc( '#', stdout );
	}while( input != '0' );
	return 0;
}

thanks....

the problem is that we have to use ANSI. Im taking a look at the code to see if i can implement it

Not sure, if that's what you want, but here the ansi version:

Code:

#include <stdio.h>

int main( void )
{
	int input;

	do{
		input = getchar();
		if( input != 'a' )
			fputc(input,stdout);
		else
			fputc('#' stdout);
	}while( input != '0' );
	return 0;
}

HTH,

Whatever happened to "Post what you have so far....." ?

helpme · 10-19-2003, 05:03 PM

It seems that when i try to run the code that was given in ANSI above i get a

" fatal error C1010: unexpected end of file while looking for precompiled header directive"

anyone knows what that means?

**Hammer** · 10-19-2003, 05:08 PM

I assume you're using MSVC6. Turn off precompiled headers in the project options. There's been plenty of threads on this before, try searching for one if you get stuck.

helpme · 10-19-2003, 05:41 PM

thanks for the info.. but i have one question

how do i do that

im new with c so i hope that you guys would cope with me

So is he having a problem with searching the board or turning of precompiled headers?

helpme · 10-19-2003, 07:40 PM

prblem solved . i was getting the error since i copied and paste the code..

i manually entered the code and the program ran fine
thanks

helpme · 10-20-2003, 04:30 PM

i figured out how to make it edit more than one character.

what i am stuck on now, is to assign differnt character different symbols.

lets for a , we will have #
and for b. we will have $

i reached a stage where all the charcters sepcified will have the same symbol placed for them, so a and b will have #.

Well you could do as someone suggested, oh, and the rules tell you, and post your code so far. But since no one ever actually follows the forum rules, do something like this:

Code:

if( foo == 'a' )
    ... put replacement character
else
if( foo == 'b' )
    ... put replacement character
...lather, rinse, repeat...

Or you could do a lookup table using an array or what not, and do it that way.

As you can see from the code below, AIOUEaioue are all converted to #.

Is it possable so that 'a' will be converted to foo while 'i' is converted to fooffooo ?

as you can see my if looops are missing something...

any suggestions?

Code:

// hardcoder.cpp : Defines the entry point for the console application.
//
#include "stdio.h"
#include "stdafx.h"

int _tmain(int argc, _TCHAR* argv[])
{
int input

	getchar();
do{
	input = getchar();
	if(input != 'a' && input != 'i' && input != 'o' && input != 'u' && input != 'e' && input != 'A' && input != 'I' && input != 'O' && input != 'U' && input != 'E') 
		fputc(input,stdout);
	
	else if (input = 'a')
		fputc('#', stdout);
	else if (input = 'i')
		fputc('@', stdout);
	else if (input = 'o')
		fputc('#', stdout);
	else if (input = 'u')
		fputc('$', stdout);
	else if (input = 'e')
		fputc('%', stdout);
	else if (input = 'A')
		fputc('^', stdout);
	else if (input = 'I')
		fputc('@#', stdout);
	else if (input = 'O')
		fputc('@#', stdout);
else if (input = 'U')
		fputc('^%^', stdout);
	else if (input = 'E')
		fputc('%$@', stdout);

		}
while(input != '0');
	return 0;
}
